What does the "warning" mean when doing detrend with DPABI

Submitted by liq2005liq on
Hi, Chaogan
 
I'm confused by a "warning" (listed in the following) when I finished smoothing and began to doing detrending with DPARSFA included in DPABI. I wondered whether the results would be influenced accordingly. Would you please give me some advice about it? My matalab is 2013 version. Thank you very much!

Hi Qiang,

You can just neglect the warning information as for now.
